Answer 1

(Данный ответ пишу на английском языке)

Answer:

(see explanation)

Explanation:

As the figure we deal with is parallelogram, it is obvious we can use a formula $S=ab\sin\alpha$, where $a=12$, $b=16$ and $\sin\alpha =0,6$ according to our task. Then the answer will be $S=12\times16\times\dfrac{2}{5}=76,8$.

Solved!
